I know he is - like I said in my reply to Ludwig, I picked a bad example. My point was that slicing doesn't _always_ produce a copy - it depends on the optimizations available to the bytecode compiler. By way of demonstration: d = [1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9] for i in range(1,10000000): s = 0 sub = d[5:10] for v in sub: s = s + v takes 25 seconds to execute, but for i in range(1,10000000): s = 0 for v in d[5:10]: s = s + v takes 19 seconds.
